About this app

Specify Brightness - Precise numerical control with a focus on safety.
Do you ever feel that standard OS brightness adjustment is too coarse? Do you want to specify an exact numerical value for your screen's illumination?
"Specify Brightness" was developed to provide the ideal brightness you need with precise, intuitive control.

【Key Features】
● Precise 1% Adjustment Featuring a unique arc-shaped gauge that fits your fingertip. You can confidently make "that extra 1%" adjustment while seeing the exact numerical value—something difficult to achieve with standard seek bars.
● Safety First for Low Brightness When specifying ultra-low brightness (15% or less), the app displays a two-stage confirmation dialog. This user-friendly design prevents accidental blackouts where the screen becomes too dark to operate.
● One-Tap Switching (Shortcut Creation) Place shortcuts for specific brightness levels directly on your home screen. Switch to your favorite settings instantly without even opening the app. (*Unlocked by watching a rewarded ad).
● 5 Theme Colors Choose from five vibrant themes, including Orange-Red, Sky-Blue, and Leaf-Green, to match your mood or style.
● Optimized for All Devices Perfectly balanced for both smartphones and tablets (7-inch to 10-inch). The layout uses a calculated "Golden Ratio" to ensure ease of use even on large screens.

【Recommended For】
•Users who want to dim the screen to the limit at night.
•Those who want to manage their favorite brightness levels with exact numbers.
•Frequent switchers between specific settings (e.g., for reading or watching videos).

A simple yet sophisticated tool that reaches the parts others can't. Support your mobile life with safety and comfort.
